Product Description

Structural Features
⚙️
To meet the demands of modern precision manufacturing for multi-functional integrated machining, this machine combines high-rigidity structure with advanced functional features. At its core is a heavy-duty sleeve-type spindle system with an integrated design, featuring five imported high-precision spindle bearings (three at the front and two at the rear). Driven directly by a high-power spindle servo motor, it delivers high-precision, high-rigidity output and exceptional speed stability, even under heavy-duty cutting conditions.
🏗️
The machine features a 30° slant bed design, integrated-cast from high-quality resin sand cast iron with a dense and rigid internal rib structure. This design philosophy provides the machine with exceptional static and dynamic rigidity as well as outstanding vibration damping, creating a stable platform for precision machining. The slant bed layout, combined with a large-diameter chip discharge port, ensures highly efficient evacuation of chips and coolant while optimizing workpiece setup and operator ergonomics.

The motion system is engineered for high-speed and high-precision performance. Both X and Z axes utilize a combination of high-rigidity linear guideways and precision pre-stretched ball screws. The servo motors are directly coupled to the ball screws via flexible couplings. Integrated with an automatic intelligent lubrication system, the guideways and screws receive optimal lubrication and cooling even during high-speed operations (up to 30m/min rapid traverse), effectively minimizing thermal errors and ensuring superior positioning and repeatability.
🔧
The hydraulic system is equipped with high-performance variable displacement pumps and solenoid valve groups from premium suppliers. Supplemented by an independent air-cooling circulation unit, the system ensures stable oil temperatures, low noise levels, and high reliability during long-term continuous operation. The tooling system offers versatile options: the standard linear gang tool post provides a simple, high-efficiency solution for rapid processing.
The defining highlight of this machine lies in its powerful turn-mill multi-tasking capability. By integrating a servo spindle and optional radial/axial servo power heads with Y-axis functionality (featuring imported precision gear transmission for high rigidity, high accuracy, and low noise), combined with the infinite C-axis indexing, the machine transcends traditional turning boundaries. It can perform complex side and face drilling, tapping, milling, and engraving operations, achieving a true 'One-Setup, Complete Machining' workflow and significantly shortening the production cycle. KEY FEATURE
🛡️
The machine exterior features a modern fully-enclosed housing design, offering an elegant aesthetic combined with superior sealing performance to effectively contain coolant and chip spray. Each sliding door is engineered with a lightweight balanced design for effortless operation. Integrated with safety interlock switches, the enclosure perfectly harmonizes operational safety with user convenience.

Frequently Asked Questions
Q What is the key difference between the NXX-46CY and NXX-46BCY models?
A The NXX-46BCY is a larger-capacity variant featuring a bigger swing diameter over the bed (Ø550 vs Ø400), greater Z-axis travel (360mm vs 260mm), a servo rotary turret with up to 12 tools (vs gang-type tooling with 4–5 tools), and a higher total power consumption of 15Kw. It is better suited for heavier and more complex workpieces requiring more tool stations.
Q What operations can the turn-mill multi-tasking capability perform?
A Thanks to the integrated servo spindle, optional radial/axial servo power heads, Y-axis functionality, and infinite C-axis indexing, the machine can perform turning, drilling, tapping, milling, and engraving operations in a single setup. This "One-Setup, Complete Machining" approach significantly reduces production cycle times and improves accuracy by eliminating re-clamping errors.
Q What are the advantages of the 30° slant bed design?
A The 30° slant bed, cast from high-quality resin sand cast iron with a dense internal rib structure, provides exceptional static and dynamic rigidity along with outstanding vibration damping. Combined with the large-diameter chip discharge port, it ensures efficient chip and coolant evacuation, improves workpiece accessibility, and enhances operator ergonomics during long production runs.
Q How does the machine ensure high positioning accuracy and repeatability?
A Both X and Z axes use high-rigidity linear guideways combined with precision pre-stretched ball screws directly coupled to servo motors via flexible couplings. An automatic intelligent lubrication system maintains optimal lubrication and cooling at all times. These features together achieve a repeatability accuracy of ±0.0025mm on both axes, with spindle radial and axial run-out kept to ≤0.003mm.
Q What type of hydraulic system does the NXX-46CY series use, and why does it matter?
A The machine uses high-performance variable displacement pumps and solenoid valve groups sourced from premium suppliers, supplemented by an independent air-cooling circulation unit. This configuration ensures stable oil temperatures, low operating noise, and high reliability during long-term continuous production — all critical factors for maintaining consistent machining quality in demanding manufacturing environments.
Q What safety and ergonomic features does the machine enclosure provide?
A The machine features a modern fully-enclosed housing with superior sealing to contain coolant and chip spray. Each sliding door uses a lightweight balanced design for effortless one-hand operation and is equipped with safety interlock switches to prevent accidental access during machining. This design balances operational safety with user convenience, meeting international safety standards for CNC machine tools.
